Leak-Free Performance

Our Flush Port Quick Connects are engineered with a double O-ring design that ensures a tight, leak-free seal every time. Note: Yamaha and Honda models feature double O-rings in the male segment while the Mercury and Suzuki feature a proprietary design with one O-ring each in the male and female segments.

Female Quick Connects

FLUSHMASTER offers the only marine-grade female quick connect available on the market. Designed with a marine-grade 316 stainless steel (SS) spring, this quick connect is built to resist rust and corrosion. No other female quick connects on the market are made to this standard.

Hassle-Free

No more wasting time screwing around with your OEM flush port plug. Our Flush Port Quick Connect permanently replaces the OEM, giving you convenience instead of a headache.

Saves Time

Get a quick connection every time you go to flush your outboards. Twist off the cap, connect the hose, flush, disconnect, and twist the cap back on. It’s that easy!

Love Love Love it.

I struggled with the price and tried desperately to find an alternative to Sea Mule to no avail. I pulled the trigger and bought a flush port and WOW, I couldn’t be happier. I’m definitely a fan a can totally appreciate this devise for what it is. I still think it’s overpriced but performance takes some of the sting out of it.

Overpriced

It’s a nice product but still a piece of plastic that is way overpriced
